Patent EP-0287838-A2 (EP)
Inventor: MACHIDA AKIRA
IPC: B65G54/02
Filed: 1988-03-24
Abstract: The wafer transporter of the invention comprises a plurality of plane electrodes (1-1,...1-5) which are horizontally coplanar with each other. The plane electrodes (1-1,...1-5) face the wafer (6) to be transported. A plurality of air nozzles (7) are provided through the electrodes (1-1,...1-5), and air is blown off from the nozzles (7) perpendicularly toward the wafer (6) surface. A voltage is applied between the electrodes (1-1,...1-5) facing the wafer (6). The applied voltage is divided by the capacitances between the wafer (6) which is electrically conductive and the electrodes (1-1,...1-5), thus the wafer (6) is attracted vertically toward the electrode, but stays without friction at the balance of the repulsive force of the air blow and the attractive force. On the other hand, the divided voltages become unequal caused by the difference of the wafer's area facing respective electrodes (1-1,...1-5). This voltage difference produces a horizontally attractive force to move the wafer (6) in a horizontal direction. The wafer (6) is forced to stay at a balancing point where the induced voltages are equal. This is used to prevent the wafer (6) from deviating from the course. Successive switching of the voltage application to a next electrode in the direction of the wafer's move allow the wafer (6) to travel along the row of the electrodes (1-1,...1-5).

Abstract: Known mould elements have a level mould board and a multiplicity of feet arranged on the underside of the mould board. With stable mould elements, there is the problem that, depending on the nature of the bare floor, not all the feet stand on the bare floor. After its completion, the false floor is then hollow at these points and is thus less able to bear loads. With other mould elements, use is made of a relatively thin foil which is filled with fluid screed. However, it is not possible to walk on the foil when pouring the screed. To overcome these disadvantages, a mould element is proposed on the underside of which three feet are attached in a triangle-like arrangement. The false floor is produced by laying a multiplicity of such mould elements, to which a screed is applied. This ensures that all the feet of the false floor stand on the bare floor. The mould elements are used in the retrospective construction of false floors, in particular for floor installations. <IMAGE>

Abstract: A supported catalyst for polymerizing 1-olefins, for example, ethylene, is prepared by depositing a chromium compound and a titanium compound on a refractory oxide support which is substantially non-spherical, and which has a relatively broad particle size distribution range. The catalyst is preferably combined, either outside of the polymerization vessel or  in situ , with a sufficient amount of at least one magnesium composition of the formula RMgR′, where R and R′ are the same or different and they are C₁ to C₁₂ hydrocarbyl groups, to provide a molar ratio of magnesium to chromium in the catalyst composition in excess of 1.25:1 to 25:1. The resulting catalyst composition has good feedability and fluidization characteristics, and it produces resins of relatively high HLMI at relatively low temperatures. 
     There is also disclosed a process for polymerizing 1-olefins, at relatively lower temperatures than was heretofore possible, to obtain resins of relatively high HLMI, using the above-identified catalyst composition. The resulting polymers can be used for the fabrication of blow-molded products, e.g., household and industrial containers.

Abstract: The object of the invention is to provide saw blades having abrasive cutter segments which will wear non-uniformly so as to provide a concave wear surface and to thereby minimize blade path deviation, i.e. lateral vibration of the saw blade. 
     Figure 2 illustrates a preferred embodiment of a cutting segment for use on saw blades for cutting granite, marble, filled concrete and other hard materials. As can be seen, the concentration of diamond cutting elements (1) in the centre section (2) is preferably about the same as the concentration of diamond cutting elements (1) in the side sections or matrices (3). It should be appreciated, however, that a larger or smaller concentration of diamond cutting elements (1) can be employed in the centre section (2) without departing from the spirit or intended scope of the invention. For example, it is expected that in some applications it may be desirable that the concentration of diamond cutting elements (1) in the centre section (2) be greater than the concentration of diamond cutting elements (1) in the side sections (3). The most important consideration in the practice of the invention is that a non-uniform cutting rate be achieved by including an effective amount of abrasion-resistant particles (4) in side sections (3). Saw blade segments manufactured with abrasion resistant particles (4) in side sections (3) will exhibit concave wear and will form a ridge on stone workpiece (5) as shown in Figure 2. It is the presence of this ridge which minimize the ability of the saw blade to deviate from its cutting path. 
     Any suitable particles may be utilized as the abrasion-resistant particles (4). However, it has been found that diamond, CBN and tungsten carbide particles are particularly effective. 
     In general, the abrasion-resistant particles (4) should be less than about 80 mesh. Of course, the optimum mesh size for a particular application can be determined without undue experimentation. The concentration of abrasion-resistant particles can also vary depending upon the particular application, but a concentration of from about 0.10 to about 0.35 carats per cubic centimeter has been found to be effective.

Abstract: In a regulating device (10) for controlling a manipulator, the manual force (F) applied by the operator at the hand lever (15) is detected by a force sensor (16). Said manual force (F) is fed as the actual force value (Ux) to a force regulator (18) and compared to a prescribed desired value (Uw). Depending upon the sign of the system deviation, the servo-drive (11) and thus the mass (14) is moved in one or the other direction. The movement comes to a stop if the manual force (F) is matched to the prescribed desired value (Uw). The operator works at a very much lower force level, which is fixed only by the desired force value (Uw) and is independent of the coupled load (14). In this way, heavy loads can be moved very sensitively and without bodily strain. <IMAGE>

Abstract: The present invention encompasses a new class of rhenium 1,1-dithioacid complexes and their method of preparation. The complexes have the general formula [L₂Re(µ-S) ]₂ wherein L is a dithioacid or similar ligand, and µ denotes the fact that the sulfur atoms in the core of the complex bridge the two rhenium atoms in the complex. Thus, the core structure for such typical compounds is generally of the form:
      where the dangling valences are associated with the sulfur atoms of a 1,1-dithioacid, L. 
     The complexes are prepared by mixing a nonaqueous solution of a tetrathioperrhenate with a disulfide which, upon reduction, gives a 1,1-dithiolate ligand, until the complexes are formed.

Abstract: The document preparing system in accordance with the present invention comprises: input processing means for detecting the per-unit-time moving amount of a click such as a mouse and for supplying information to be used for calculation for correction; correction means for executing a calculation for correction based on informa­tion supplied from the input processing means and for supplying a corrective value; and mouse cursor moving amount calculation means for calculating the per-unit-­time moving amount of a mouse cursor using the correc­tive value and the per-unit-time mouse moving amount. 
     According to the present invention, as the mouse moving speed is higher, the mouse cursor moving speed is further increased. This enables to closely reproduce the mouse user's operation feeling that a fine movement of the mouse is slowly made while a rough movement thereof is quickly made. This improves a smooth operational ef­fectiveness of the mouse.
